no....
just because someone works hard and earns good money does not entitle them to have to pay any more for their child IMO....
(considerin he has her half the time)
children cost the same to raise wheather their parents earn more or not
my dh is in this position and its totally unfair... just because he earns more should not mean he pays more than 50%
his ex asks him for money all the time and asks to go 50% but then asks for more on top and coz he cares so much he pays out on top o his child support... needless to say that stopped when his ex rang him crying poor the posted a pic of her new $200 tattoo on FB of her new husbands name who she is also creaming money off
if two ppl dtd... it took two and thats 50% lol
also the fact that hes already paying half of private school fees is pretty damn nice ... a lot of men def wouldnt
quite frankly the question in itself to me sounds totally greedy ... sorry but it hit my buzzzer a bit
